“…Similarity and differences in the neuromuscular control were demonstrated between the groups with CP and with TD and were similar to previous findings [6,11,12,24,25]. The predominance of anterior-posterior/proximal-distal patterns of activation were seen in all participants with a greater variety of patterns seen in the group with CP.…”

“…Younger children (6-8 years old) [12] and all children with CP [11] demonstrated increased variability as compared to the older children (10-12 years old) with typical development (TD). This variability resulted in poor test-retest reliability of EMG patterns (Cramer's f = 0.40 and 0.48 for groups who were typically developing [TD] and CP respectively).…”

“…For example, children with cerebral palsy have demonstrated deficits in anticipatory mechanisms (feedforward postural adjustments) [14][15][16][17][18], adaptive mechanisms (feedback postural adjustments) [3,14,[19][20][21], musculoskeletal systems (muscle force and range of motion required for standing balance) [22] and sensory systems (visual and proprioceptive function required for balance) [23,24]. This research illustrates well how one population can experience a broad range of postural control problems, and also that there is an absence of a comprehensive clinical assessment for children.…”

This study evaluated the intra-rater, inter-rater and test-retest reproducibility of the FullBESTest and Mini-BESTest when assessing postural control in children. Thirty-four children aged 7-17 years participated in intra-rater and inter-rater evaluation, and 22 children repeated assessment six weeks later for evaluation of test-retest reliability.Postural control was assessed using the Full Balance Evaluation Systems Test (FullBESTest) and the short-form Mini-BESTest. Intra-rater, inter-rater and test-retest reproducibility were examined using video assessment. Test-retest reproducibility was also assessed in real-time. Reproducibility was examined by agreement and reliability statistics. Agreement was calculated using percentage of agreement, Limits of Agreement and Smallest Detectable Change. Reliability was calculated using Intra-class Correlation Coefficients. Results showed that the reliability of Total Scores was excellent for the Full-BESTest for all conditions (all ICCs>0.82), whereas the MiniBESTest ranged from fair to excellent (ICC=0.56 to 0.86). Percentage of Domain Scores with good-excellent reliability (ICCs>0.60) was slightly higher for the FullBESTest (66%) compared to the Mini-BESTest (59%). Smallest Detectable Change scores were good to excellent for the Full-BESTest (2% to 6%) and for the BESTest (5% to 10%) relative to total test scores. Both the Full-BESTest and MiniBESTest can discriminate postural control abilities within and between days in schoolaged children. The Full-BESTest has slightly better reproducibility and a broader range of items, which could be the most useful version for treatment planning. We propose minor modifications are recommended to improve reproducibility for children, and indicate the modified version by the title Kids-BESTest. Future psychometric research is recommended for specific paediatric clinical populations.

“…When challenging the proprioceptive system, such as standing on a soft surface, children with CP demonstrate increased variability in anticipatory postural adjustments when compared to TD children (Westcott, Zaino, Miller, & Thorpe, 1997). These studies demonstrate that children with CP use visual and proprioceptive information differently and less effectively when compared to TD children.…”

Postural control in children with cerebral palsy: a comprehensive definition, framework and reproducible assessment.

Background: Cerebral Palsy (CP), the most common cause of childhood physical disability, results from a brain injury in utero or during infancy and presents as a primary impairment in movement and postural control. Impairment in postural control is known to have a significant impact on activity and participation of children with CP. Despite this, there is no current consensus on the most optimal assessments and interventions for this core deficit of CP. Aims: Thesis aims were in three parts: (Part 1) Evaluate current postural control assessments and interventions -Studies 1 and 2; (Part 2) Assess the reproducibility of a comprehensive clinical assessment of postural control in children with CP -Studies 3 and 4; (Part 3) Assess the validity of postural control assessment items in children with CP -Studies 5 and 6. Study 1 (Chapter 3), a systematic review of the efficacy and effectiveness of exercise interventions to improve postural control for children with CP, was performed using AACPDM and PRISMA methodology. Six databases were searched using ("cerebral palsy" OR "brain injury") AND (postur* OR balance OR "Postural Balance" (MeSH)) AND ("intervention" OR "therapy" OR "exercise" OR "treatment"). Included were 45 articles describing 13 exercise interventions purported to improve postural control in children with CP. Evidence for interventions was moderate (five interventions), weak or conflicting (six interventions) or none (two interventions). No intervention reached a high level of evidence highlighting the need of a defining framework and a comprehensive postural control assessment. Study 2 (Chapter 4), a Delphi study was designed to identify consensus on a definition, a framework, and assessments and treatments for postural control dysfunction in children with CP. The perspective of 43 international researchers and/or clinicians with a mean of 20 years experience was gathered. Consensus was achieved for a postural control definition. A comprehensive postural control framework (Systems Theory) and multi-item assessment tool (Balance Evaluation Systems Test: BESTest) was identified. Further research was needed to determine whether this test could be applied for children with and without CP. Study 3 (Chapter 5) sought to establish the reproducibility of the BESTest and the Mini-BESTest in 34 typically developing (TD) school-aged children, seven to 17 years. Excellent reliability was observed for the BESTest (ICC >0.82) and fair to excellent for the Mini-BESTest (ICC 0.56 to 0.86). The Smallest Detectable Change (SDC) was good to excellent for all BESTest agreement Other publications during candidature Conference abstracts -Peer reviewed and published
